I'm not sure, but it looks like Kalanchoe luciae. If so, those blooms will spell the end of it. They are monocarpic.

I see lots of pups there:).

@mesembs All the photos online I find Kalanchoe Luciae show green paddles, whereas these were a lemon yellow everywhere with no green tint. Maybe this one is a close cousin?

Does Luciae flower in approximately the same way?

@kara so the pups of this plant form at the top instead of to the sides? You just cut those off at the base and wait for a callous to form and then use root hormone to grow out a root?

If you keep the plant in high sun, it would show some pretty highly colored paddles... It is possible that it could be a different Kalanchoe.

The flowers look pretty much like this from the internet photos I can find. I don't grow these though, so I don't know for sure.

Yep just cut at the base of the pup. Let callus and stick on top of some mix. With these guys you wont need rooting hormone. I find roots form pretty fast on these guys:). Obviously no water or harsh sun till roots form.

@crenda, I too would vote for Kalanchoe Thyrsiflora. Notice in my photo how the stems do NOT come up from the center. Multiple stems arch around the sides of the plant and then go up.

Not thyrsiflora. Luciae for sure. K thyrsiflora has very short flower stalks with bright yellow flowers... and paddles have far less color and smaller in size (and plants are extremely rare on top of that).

@palmbob, but then how do you explain that the photos of blooming Luciae all show a single stem that is directly centered on the plant versus my original photo that clearly shows multiple smaller stems creeping up the side near the top of the plant?

Flowers can arise from suckers on sides as well as the centers. Those plants look severely dehydrated (hot there?) so have found a different pathway to their flowering before they die altogether (these are monocarpic). When a plant goes into a blooming event, sometimes the entire plant blooms. Not every individual does the same thing as the other. I have seen a large many variants of how this plant grows depending upon its care and climate. Same goes for a lot of succulents, particularly monocarpic species. This is their last and only chance to spread their DNA so some of these plants may alter from the norm, particularly in untoward situations (too hot, too dry, injury etc.) to still manage to flower.

In my yard I had a monocarpic species of Agave (98% are monocarpic) flower but failed to produce any offsets (yet)... so it 'hung on for 3 more years, flowering 3 more times but all from the root stock (happens, but rare)... finally suckers were produced and it gave up. Definitely NOT in the playbook of standard flowering behavior, but it did what it needed to to pass on its DNA.

Thanks, Palmbob. Like I said, I don't have a thyrsiflora and I knew it was quite uncommon. It never dawned on me that the blooming may look different under different growing conditions. It should have, since the plants can do so.

Here are a few shots of Kalanchoe luciae in different conditions showing how this species adapts and varies to them.
